Answer:
The Sum of the measures of the interior angles of a triangle is 180°
Step-by-step explanation:
Answer:
f(g(-7))
Step-by-step explanation:
Rewrite in slope intercept from y=mx+b y=1-3x+11/3
According to Pythagoras theorem
a^2+b^2=c^2
similarly ,
3^2+ 4^2= 5^2
9+16=25
25=25
LHS=RHS
so angle of triangle is 30 , 60 and 90
answer is 3,4,5
